ROBERT W. MAOGOWAN, OF NEV YORK, N. Y.

FANNING DEVICE FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No 333.767, dated January 5, 1886.

Application filed October 18, 1884. Serial No. 145,842. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT W. MAoeowAN,

I of the city, county, and State of New York,

have invented a new and Improved Fanning Device for Railroad-Oars, &c., of which the following is a full, clear, and exact description.

This invention has for its object the production. of a simple and readily attachable and detachable rotary fanning device, applicable to the side windows of railroad-cars or other vehicles in rapid motion, and which shall be driven by the resistance of the air encountered by the moving train or vehicle, for the purpose of introducing a fresh and cooling current or currents of air through the particular window to which the device is applied.

To this end the invention comprises both an outside current or driving wheel and an inside fanning-wheel on opposite ends of a shaft uniting the two, and means for holding the same in position by the closing of the window-sash and for adjusting the device as required, substantially as hereinafter described.

lteference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a vertical transverse section of the side of arailroad-car body in part through one of its side windows, with a fanning device embodying my invention applied. Fig. 2 is a plan of said fanning device detached. Fig. 3 is a face view of the current driving-wheel, and Fig. 4 a transverse section on the line 00 a: in Fig. 2, looking toward the fanning-wheel.

A indicates the window-frame portion of a railroad-car body, B being the window-sill, and G the window-sash.

D is an elongated box, in which a shaft, b, is fitted to freely turn, and which, when the fanning device is applied to the car-window, rests upon and across the window-sill B, and is held down thereon by the sash O. This box or the shaft 12, which it carries, projects sufiiciently on both sides of the window to carry on the outer end of the shaft a current or driving wheel, E, and on the inner end of said shaft a fanning-wheel, F. The driving-wheel E may be of ordinary or any suitable construction that will cause it to be rotated in afixed direction by the resistance encountered by the air when the car is in motion in either direction of travel or by a sidewise current. Thus it may be made up of a series of scroll or bucket like radial blades, d, constructed and arranged to present outside concave and inner convex exposures, as in other current-wheels, for rotating in a given direction in opposite or different directions of resistance. The fanning-wheel F on the inside of the car may be composed simply of a series of angularly-arranged blades disposed so that when said wheel rotates or is driven by the wheel E in a given direction the fresh air from the outside of the car will be forced into the interior thereof and against the occupant or occupants of the seat or seats adjacent to the window, thus affording a pleasant relief in warm weather and ventilating the car.

To hold the fanning device steady and to adjust it, as required, to different thicknesses of windows-ashes, the box D, down on which the sash O closes, is provided with a clamp, which grips opposite sides of the lower end of the sash, and which is or may be composed ofa fixedjaw, e, and an adjustable jaw, f, secured by a set screw, 9. This clamp will serve to hold the fanning device in a fixed or proper position, free from all liability to be turned askew or out of line by the resistance of the current of air.

By means of the fanning device as described, and which may be applied or removed as required, an opportunity is afforded for introducing a forced current of fresh air through a particular window of the car, to the relief of passengers in its immediate vicinity,without inconveniencing or annoying the other passengers of the car, and any number of the windows of the car may be thus fitted with a fanning device, as circumstances or the wants of the passengers or condition of the weather may require.

Having thus described my invention,whatI claim as new, and desire to secure by Letters Patent, is-

In railway-oars, the independent automatic 5 and removable fanning device consisting of the box D, for receiving and holding the shaft 1;, the driving wind-Wheel E and inner fan, F, and the adjustable clamps e f, secured to the boxD, for receiving and clamping the lower edge of the window-sash, the whole resting ro upon and supported by the Window-sill, substantially as set forth.
